How Much Current is Enough?
Measuring low resistance – which is usually taken to mean resistance of less than 1Ω – has many
applications, from checking the condition of circuit breaker contacts to verifying the integrity of
welds in metal structures. One very common question however is, “What’s the best test current
to use?” As is usual with questions like this, there is no simple “one size fits all” answer.

Breaker Failure Testing
When a breaker fails to open contacts or interrupt current after receiving a tripping signal from a
primary relay, we have a breaker failure. Most protection systems have a breaker-failure scheme
and it is important to test this backup protection as part of your regular relay testing program.

Locating Battery Ground Faults
Ground faults often develop in substation battery systems over time due to environmental factors
and maintenance activities. Dirt and debris accumulated on battery surfaces can create electrical
paths to the battery rack. Electrolyte residue due to cracking or crazing of the battery container
also results in conduction paths to the battery rack. This application note will cover how to use
the Megger BGL to trace and locate ground faults on a live DC system, without sectionalizing
any circuits.

Cable Insulation Resistance Testing
Insulation is used in cables to protect the conductor and to ensure that there is no connection
between the two current carrying components of the cable – the conductor and the metal screen.
Three commonly used dielectrics for High and Extra-High Voltage cables are impregnated multilayered paper, oil filled paper and extruded polymer. A simple insulation resistance test is the
easiest and fastest way to determine the insulation condition of both new and old cables.

Megger designs and manufactures portable electrical test equipment in factories located in
Germany, Sweden, the UK, and USA. Megger products help you install, improve efficiency,
reduce cost and extend the life of your or your customers’ electrical assets.
Established in the late 1800s, the company has been designing and making test and measurement
instruments that perform electrical measurements for preventative maintenance, troubleshooting
and commissioning for decades. Megger products have supported customers all over the world to
improve their facilities’ efficiency, reduce costs, extend the life of apparatus and through
trending and analysis, anticipate equipment failure and future performance. It now has local
offices in many locations with technical support teams and distributors all over the world.
Working with customers
Megger believes that by working closely with customers it can deliver the best customer
solutions and after-sales service today, and in the future. Megger is committed to anticipating
client needs by listening to customers and industry specialists while continually investing in
innovative research and development, design engineering and manufacturing techniques.
Megger brand
Our strategy is to produce all our products with a single brand name, Megger. The advantages to
you are that you know the products and software will work well together, and all the products
have a similar yet distinctive 'look and feel' with their dark and light grey casings. We don't
waste colour on trying to make our test instruments pretty – we reserve it for useful functions
such as range selectors and displays. Our design engineers come from many different nations,
and they regularly exchange ideas and tips with colleagues from other countries. That means you
get the latest innovations, one of the reasons that Megger products are so advanced. As more
companies join the Megger family, you may find some test equipment sold by us that have not
yet transitioned to the Megger identity system. Don’t worry – our top priority is ensuring that
product quality is right. We’ll get round to making sure the colours are the same later.
How the greatest brands in test and measurement came together
Our systems are geared to keeping things local – localised engineering, localised marketing,
localised decision-making. Our employees are proud of the companies and brands that go to
make our company history and many of these names are still trademarks or registered trademarks
of the company in many countries.
